Airborne CX/LD20 water depth measurement laser radar system

Airborne CX/LD20 water depth measurement laser radar systemBy using a high-frequency 532nm laser, high point density detection of land and seabed landforms can be achieved, with a scanning angle of up to 40 °. It has the advantages of large scanning width, high operational efficiency, and low cost. This product has been deeply optimized in terms of lightweight and miniaturization, resulting in a total weight of only 6kg and a volume that can be adapted to fixed wing and multi rotor unmanned aerial vehicle flight platforms, enabling fast and large-scale operations.

Performance characteristics:

Capable of integrating land and sea terrain surveying and mapping;

Strong detection capability and adaptability to water quality conditions, which can better adapt to the domestic water quality situation;

Weighing only 6kg, it can carry various unmanned aerial vehicle platforms such as small and medium-sized ones;

Built in large capacity storage, capable of one click operation;
